On Spirit Airlines, pets in the cabin are allowed provided they fit comfortably in their carrier. The carrier must fit under the seat in front of you. Due to the airline’s pet policies, Spirit is popular with passengers looking to cut costs on their trips. The absence of checked baggage or cargo flight options may limit cabin pet availability, so it is best to make your reservations as early in the planning process as possible. 

Spirit is committed to accommodating passengers and pets in the cabin, but they prioritize the safety of everyone on board. To ensure you can successfully fly with a pet in the cabin of a Spirit Airlines flight, here is the information you need.

How to Book a Carry-On Pet Reservation with Spirit Airlines 

To add a pet to your reservation, the airline recommends contacting the Reservations Center at 801-401-2222. Spirit recommends making these arrangements in advance, as there is a maximum of four pet containers per aircraft on all domestic flights. You may add a pet to your ticket upon check-in, but this is highly discouraged. The $110 fee will be collected at the counter.

More FAQ Info for Pets in the Cabin 

 

Are there any pet conduct rules in the cabin?
The pet cannot be ill, violent, or in physical distress while aboard the aircraft. If the animal becomes offensive or causes a disturbance prior to leaving the gate, it will be removed. Additionally, the pet must be harmless, inoffensive, odorless, and require no attention during the flight. He must remain under the seat and inside the container for the duration of the flight, including taxi.  

 

Are there any other pet travel options?
No. Spirit does not transport pets in cargo at any time.  

 

Are there any weight restrictions?
Yes—the combined weight of the animal and carrier cannot exceed 40 pounds. This is double the weight of what some airlines allow, but it does not mean large dogs can fly on the airline. It is essential to test the recommended carrier size before making any flight decisions. 

 

What should I know about carry-on pet carrier restrictions?
The maximum carrier size is 18”L x 14”W x 9”H. We recommend using a soft-sided carrier, as it will fit more easily under the seat in front of you. The animal must be able to stand upright and move about comfortably within the container. It should be well-ventilated and have a spill-proof bottom in the event of an accident. The pet must remain in the pet carrier at all times while on the aircraft.  

Each passenger is limited to one pet carrier, but the container may fit up to two small pets. The fee applies to the container, not the number of animals inside. Passengers will not need to pay an additional $110 for an extra pet.  

 

What does “household bird” mean?
A household bird is any bird you may keep as a pet in your home. Those not considered to be household birds include: farm poultry, waterfowl, game birds, birds of prey, and flightless birds. Passengers should note that flights traveling to and from Puerto Rico, St. Thomas, and the U.S. Virgin Islands do not permit birds.
